Weather strip and sash mounting



Patented Ja11.5, 1943 `'UNITED STATES PATENT :OFFICE WEATHER STRIP sAsH MOUNTING Arthur M. Starck, Springdale, 001111.. Application February 24, 1941, seria1No. 380,266

1 claim. ,(011,20-121- This invention relates to window constructions and relates more particularly to parting strip constructions for window jambs which permit ready removal or tilting of the window sash or sashes to facilitateaccess to the eXteriors thereexterior of such sashes from the interior of the building for washing or cleaning, numerous constructions have been suggested for demountably supporting the 'sashes in the jamb or for swinging the sashes vrelatively to the jamb.

The present invention has as an object the provision of an improved form of parting strip for window constructions which permits ready removal or swinging of the window sashes. k

Another object' of the invention is to provide an improved form of parting strip which may be easily assembled' and disassembled in order to facilitate its installation an'd'repair.V

A further object of the invention is to provide a parting strip which is simple in construction, positive in its retention of the window sashes and which acts to seal the sash in weather-tight relationship to the jamb.

Other objects of the invention will become apparent from a description of a typical form of the invention.

For a better understanding of the present invention reference may be had to the accompanying drawing in which:

Figure 1 is a view in vertical section of the typical form of window construction embodying the present invention; and

Figure 2 is a view in section taken along line 2 2 of Figure 1.

Parting strips of the type embodying the present invention are illustrated in the drawing as applied to the type of window sash and counterbalance construction disclosed in my copending application Serial No, 373,886, led January 10, 1941. It will be understood, of course, that the parting strip construction may be applied with equal facility to other types of window constructions.

As best shown in Figure 1, a typical form of window having a parting strip embodying the present invention applied thereto may consist of vertically slidable sashes II and I2. The sashes II and I2 may be supported in any intermediate position by means of spiral type counterbalances I3 of well-known form. These counterbalances are provided with rods, not shown, to which arev pivotally secured hinge-like elements I4 which permit the sashes to be rotated or swung about their lower edges from a vertical position to the horizontal dotted line positions shown in Figure 1.

'The sash II may. be normally retained' in its vertical position by means of a guide member I5 which consistsv of 'an elongated strip disposed in a recess IG'in the jamband normally urged outwardly to overlap the edge of the sash II by means of a plurality of springs I'I. The outer sash I2 isv prevented from swinging outwardly by means of'a facing strip secured to the outer edge of the jamb and overlying the edge ofthe sash I2.

The constructionv described above permits swinging movement of the inner sash II from a vertical .to a horizontal position by pressing the strip I5 into the recessv I6.

IfV a parting strip of conventional'form, that is, a strip nailed yto the jamb, were provided'between'the sashes it would 'not'be possible to swing the outer sash inwardly because the parting strip would block inward movement of the sash I2.

In accordance with the present invention a parting strip construction I8 is provided which may be moved into a position flush with 'the inner surface of the jamb Ill, thereby permitting the sash I2 to be swung into the room when lowered to the dotted line position and the inner sash II is swung inwardly.

At best shown in Figure 2, a typical form of parting strip I8 embodying the presentinvention may consist of an elongated channel member I9 which is adapted to be secured in a recess 20 between the spiral balances I3 by means of screws 2 I. The channel member preferably is of unitary construction, but, if desired, it may be made up of a plurality of parts. The side walls 22 and 23 of the channel member are provided with in-` wardly directed anges 24 and 25 which are inclined at an acute angle to the respective side walls.

Cooperating with the channel member I9 is an elongated shell member 26 formed of resilient material which is provided with a central generally rectangular raised portion 21 forming the parting strip proper and which is of suiilcient width to be received closely between the adjacent a amb lu of sunicient width to accomodate two 55 edges of the sashes Il and I2. Outwardly of the raised portion 21 are longitudinally extending ribs 28 and 29 which are receivable in grooves 36 and 3l in the window sashes II-and I2. The shell member 26 is also provided with rearwardly projecting flanges 32 and 33 which have at their edges flanges 34 and 35 inclined generally complementally to the inclination of the flanges 24 and 25 on the channel member I9.

Interposed between the base of the channel member I9 and the shell member 26 are a plurality of springs 36 which normally urge the shell member 26 outwardly toward the open side of the channel member I9. and into engagement with the edges of the window sashes II and I2. The springs 36 may be of any desired type and may be secured to the channel member I9, for example, by soldering or by means of tabs stuck out of the bottom of the channel member,

With this construction a normally weathertight seal is maintained between the shell 26 and the edges of the sashes II and I2 and inasmuch as a constant pressure is .exerted on the edges of the sashes, rattling of the sashes in the jambs is minimized and the sashes and jamb may expand or contract due to varying weather conditions without the seal being broken.

Parting strip constructions of the type described above may be very readily installed in window jambs inasmuch asthe elements thereof may be readily taken apart and assembled. For example, the channel member may be placed in the groove 20 and ,secured in position by means of the screws 2 I. One flange, for example flange 35, of the shell member 26, may then be inserted behind the flange 24 of the channel member and the shell member 26 compressed so that the flange 34 canbe pushed by the flange 25 on the channel member thereby securing these elements together. The exibility of the side walls of the channel member I9 also facilitates the insertion of the shell member 26 into the channel member. Similarly by compressing the shell member 26 transversely, it is possible to detach the shell from the channel member I9 if it is necessary to make repairs to or replace any part thereof.

From the foregoing description it will be apparent that a simple parting strip construction has been provided which may be readily applied to window jamb and window sash constructions and which, when installed, permits ready removal or inward swinging of the outer sash into the building for access to its outer surface.

It will be understood, of course, that parting strips of the type embodying the invention are susceptible to considerable modification as to form and contour and shape and size and that they may be used for example, lto replace the strip I5, if desired, or for other purposes of similar nature, without departing from the invention. Accordingly, the form of parting strip disclosed herein should be considered as illustrative only and not as limiting the scope of the following claim.

I claim:

A parting strip construction for window jambs comprising a pair of retaining members adapted to be mounted in spaced apart, substantially parallel relationship in a longitudinally extending recess in a window jamb, inwardly extending iianges on said retaining members adjacent to their outer edges Adefining a restricted opening extending longitudinally of said recess, a combined parting and weather strip adapted to be detachably mounted in said recess, said parting and weather strip comprising a substantially U- shaped channel member having substantially parallel sidewallsl projecting inwardly between and substantially parallel to said retainingV members and a bottom interposed between said sidewalls, flanges projecting outwardly from said sidewalls behind the anges on said retaining members for retaining said channel member in said recess, a large rib of generally rectangular cross-section projecting from the middle and extending longitudinally of said base in a direction opposite to saidsidewalls and forming a parting strip, smaller ribs projecting from said base on opposite sides of said parting strip engageable with edges of window sashes on opposite sides of said parting strip to form weather strips, and means for urgingl said channel member outwardly of said recess.
